Would putting a Warrior 51/43 helix and a green spring in the secondary give my stock 04 Viper S an extra little boost? I can not seem to find the 53/43 they talk about in the tech section.
Ran one on my 02 ER. Nice little boost corner to corner and no effect on top end. Go for it 

some will say the 51/43 is theway to go. I too have been looking for the 53/43 and haven't had much luck finding one other than going brand new at $130. I tend to see the 51/43 listed for sale quite often.
apex 51/43 runs like a 48/42. your gonna overrewv like crazy; especially using green secondary spring.
Hey Turk, should I just keep the stock spring? What would you suggest doing to a stock viper to get just that extra bit of kick without spending big bucks? The helix and spring run about $150 cdn.
Here's the thing, My buddy has a Formula III 600 with stinger pipes and his wife has a stock 700 MXZ, in a lake race both are quicker out of the hole but once I reach 40-50 mph I start making a move and reach top end before them. In a short race however, they've started shutting down and I seem to just be starting to get going.
